'Here I Am' in the Bible

In what secret place may a man take cover without my seeing him? says the Lord. Is there any place in heaven or earth where I am not? says the Lord.

{Therefore} look, here I am, and I will surely lift you up and forsake you and the city that I gave to you and to your ancestors from {my presence},

As for me, here I am in your hands; do to me what you think is good and right.
